摘要： Methods for varying seal force in active seal assemblies for doors employ active materials that can be controlled and remotely changed to alter the seal effectiveness, wherein the active materials actively change modulus properties such as stiffness, or a combination of modulus and shape in response to an activation signal. In this manner, in seal applications such as a vehicle door application, door opening and closing efforts can be minimized yet seal effectiveness can be maximized.

摘要： The present invention relates to a morphing cellular structure. The morphing cellular structure comprises a group of unit cells with each unit cell configured to have a cellular geometry. The group unit cells are formed of an active material, where the active material has both a first state and a second state. The active material is responsive to an actuation signal such that when the actuation signal is actuated, the active material is deformed from the first state to the second state, thereby changing the volume of each unit cell affected by the actuation of the actuation signal and morphing the cellular structure. Furthermore, both a passive material and at least one additional active material can be attached with the active material, allowing a user to selectively change the shape of the cellular structure.

摘要： A laser metrology system for estimating the deformation of a structure is provided. The system includes a plurality of laser beam position detectors distributed across a surface of the structure. Each laser beam position detector is intersected by a laser beam and is configured to determine the change in location of the intersection point in at least one dimension. By determining the change in location of the intersection point for each laser beam position detector, the laser metrology system can calculate the deformation of the structure that caused these changes in location.

摘要： An airflow control device comprises a body and an active material in operative communication with the body. The active material, such as shape memory material, is operative to change at least one attribute in response to an activation signal. The active material can change its shape, dimensions and/or stiffness producing a change in at least one feature of the airflow control device such as shape, dimension, location, orientation, and/or stiffness to control vehicle airflow to better suit changes in driving conditions such as weather, ground clearance and speed, while reducing maintenance and the level of failure modes. As such, the device reduces vehicle damage due to inadequate ground clearance, while increasing vehicle stability and fuel economy. An activation device, controller and sensors may be employed to further control the change in at least one feature of the airflow control device such as shape, dimension, location, orientation, and/or stiffness of the device. A method for controlling vehicle airflow selectively introduces an activation signal to initiate a change of at least one feature of the device that can be reversed upon discontinuation of the activation signal.
